To ali whom it may concern:

Be it known that l. lllnnrr G. Larra., a citizen ot the United States,residing atv Syracuse.l in the county ci Onondaga and State of New York.have invented a new and useful linprovenient in rlljvpe-"llilritingggll/lachines., oi' which the iollowinn is a speci,-

lfication.

This invention re ates to improvements in typewriting1 machines` and hasfor its ob'eet to produce an eflieient and desirable ta ulatingmechanism for typewriting machines which is of compact and` siinpleconstruetion; and also to combine the tahulating mechanism with linelocking, line spacing and margin releasing; mechanisme, so that thesaine parts perform more than one funeH tion. and so that the severalparte are ar- -anged within lees space than is usually required and canbe provided at lees cost.

This application is a division of application, Serial No. (358,153,filed by nie Nov. 2, 1913., and the improvements are herein shown anddescribed in connection with the collapsible typewriter l disclosed insaid application, but the improvernents herein claimed are notrestricted in lzuniilication to collapsible typewriting machines.

they approach the platen, and which, as usual, is connected to thecarriage escapeinent, so 'to cause a letter space movement rt". 'thecarriage each time a type har is actiated to malte an impression. Theuniveiiil bar consists of a curved strip having` two parallel rigidlyconnectz-nl rearwardly extending arins c which are pivoted to the lowerends of two pairs of downiiardly extendiing` arms c"` These arins arerig'- idly attached at their uper ends to the ende of a pair of parallelrock shafts; @3 e* which are suitably journaled to lugs on a bracket e5which is secured in any suitable manner to the rear cross bar hf et themovable traine A. @ne of the arnis e2, see Fig. has an auxiliary arin elpivoted thereto and extending rearwardly to a pivotal connection with anupright link e8 which is connected at upper end to the escapeinent leverG oiE the carriae escapenient, so that the eseapen'ient is actuated hythe operatioii or the universal bar.

G represents the toothed escapeinent wheel of the carriage escapenientandy the lieed 'pinion connectedthereto. i

'lil represents the raclr bar the tance in opposite directions. i

The ends of the rack bar are secured to the rear ends of supportinglevers fr and it which are pivotally mounted on the opposite ends of thecarriage. rihesc levers preterably have inwardly extending rear endswhich are rivet-ed in slots at the ends of the rack bar. The levers hand h are pivoted by screws 7a2 or otherwise to the ends o the carriageand are provided with slots '/3 concentric'with their pivots in whichscrews or pins if, attached to the ends of the cairriage, extend tolimit the up and down movements of the rack bar. The 'forward end of thelever zy extends under the adjacent end of the platen shaft and upwardlyand outwardly in front thereof in position to be engaged and actuated bythe line space lever, presently described. A spring h5 connected to thelever h and to the adjacent end of the carriage acts to yieldingly holdthe rack bar in the normal position shown, in which it meshes with thefeed pinion.

The linespace lever, as shown, consists of an outer or handle portion land a rear journal portion I, to which the handle portion is connectedby a hinge joint z' which. permits the handle part to be swung` tor-Wardly into the operative position shown in Fig. 7 and indicated bybroken lines'in Fig. l, or to be folded inwardly in front ot the platenwhen the machine is to be collapsed. F or machines of ordinaryconstruction which do not collapse, a non-folding line space lever canbe used.

The line space lever projects forwardly from the right hand end of thecarriage on which its rear portion is journaled in a bearing and thefront end of the lever extends downwardly forming' a handle by which'the lever can be rocked a limited dis- At its rear end the lever part lis provided with a 'i head which forms inwardly and outwardly projectingarms or parts 3 and it. A leaf spring` i5, secured at its forward end tothe bearing 2, rests at its free rear end on the tlat top of the crosshead and acts to return the line vspace lever to the normal positionwhen released after being rocked in either direction,

The downturned end of the handle of the lever is suitably shaped to bepushed to the right by the thumb of the right hand in the usual way, andalso to be grasped by the thumb .and fingers and turned to the left, thethumb in this case being placed against a rest or projection e andacting to hold the carriage :@ruinst movement. or to control itsmovement by its driving!` wing, as u ill, be explained later.

The outwardly projecting; arm 'an ot the line space leverprojects over the 'trent end oif the Iaclr bar supporting lever t sothat by rocking` the line space lever in the opposite direction, that isby pulling` its depending handle to the lett, the rack bar is raised ontof mesh with the feed pinion and the carriage will be pulled to the leftby its driving spring;` as far' as permitted by the operator.

rlihe first effect of such movement ol the line space lever is torelease the carriage from its feed mechanism and permit it to be movedin either direction, lo the right by means oit' this line space leverand to the lett by its driving spring, controlled by pressure on theline space lover. 3 represents the carriage driving' spring drinn whichhas an internal operatinr;` springt as usual, and connected to thecarriage as by a strap Zt,

N and N, Figs. 3. Z and il. represent two margin stops mounted on therack bar Il, and N2 is a center stop or abutment against which themargin stops are adapted to strike to limit the travel of the carriagein both directions. ridhe margin stops straddle the raclr bar, havinglegs eii,ei'ii1;rtlie slots in the front and rear taees or the bar1whereby they are heid Jfrom movemeilt longitudinally on the bar, andeach stop is provided with a spring clip n. the tree end oi which isadapted to snap into notches a in the teeth on the rear sido of the barto releasably retain the stop in position. The margin stops are, asusual. adjustable to different positions on the rack bar.

lThe center stop ll is formed by a rearward projection on a lever a2,Fig. 9, which is )ivoted between its ends to the upper end l'iO necesa-eof an upright lever ni The lever fm2 is located in a recess in the frontside ot the bracket e and the stop N2 projects `from the leverrearwardly through the rectangular opening n4 in the bracket with itsrear end extending into the path of forwardly proyecting portions or'the margin stops. a5 is a spring` connected to the outer end of thelever n2 and to the bracket e5, and actingto yieldingly hold the centerstop N2 in the position shown in lfig. 9. 4'lhe opening n4 olE thebracket permits the stop to move one letter space to the left (right inlig., 9) after it intercepts the margin stop lil, and after suchmovement to resist any further movement of the carriage. This movementof the stop N2 swings the upper end of the upright lever n to the lei'tand places the lower end oli the lever over the rearwardly projectingendot the arm el, connected to the universal bar.r and thus locks theuniversal bar and escapeinent from aotioh, or locks the linev as it istechnically termed. li f raising` the rack bar until the margin stop Nclears the center stop, the spring a5 will move the center stop back toits normal position and then by permitting the rack bar to resume itsnormal position in mesh with thc feed pinion, the line may be continueduntilthe carriage reaches the end of its travel, il so desired. When thecenter stop N2 returns to the normal position, above mentioned, it willrest under the 'maroni stop N, and as the actuating s )ring it Y'or therack bar is stronger than tie stop actuating` spring a5, the center stopwill he de pressed byi the margin stop-into the lower part oi theopening n4, but as soon as the carriage moves in either' d ireetion farenough for the margin stop to /clear the center stop, the latter willreturn to its hermal elevation. The forwardly projecting part of'themargin stop N is made with an upwardly and outwardly inclined loweriiacen shown in Fig. 8, to permit'it to pass over the center stop when thecarriage is set back tor a new line, if it has been moved to the otherside of the stop. The other margin stop N l'nfeieerably made with asimilar but oppo; sitely inclined lace, so that after this stop has beenset for writing on the margin .of

the paper, it will not stop the carriage in its travel to the lett,

C represents a main stop for tabulating, which is adapted to interceptany one of a series oi.l` stops l? l which are adjustably placed on therack bar, and as many yoif these adjustable stops may he used desired.The traveling stops shown are provided with legs which straddle the rackbar in the notches therein and project upwardly from the rack bar.. Themain stop 0 is so located that the rack har has to be raised about twiceas :tar when tabulatinrr as for simply releasing the margin stops fromthe' center dit a stop, This additional movement of the rack bar is madeby rocking` the line space lever l to a correspondingly greaterdistance. By rocking the line space lever the proper distance to releasethe rack bar from the feed pinioinllwy carriage can be'allowed to moveto the lett past the first or any desired nunn ber of the tabulatorstops l) ll and the selected stop then caused to engage the main stop t)to stop the carriage by giving the line space lever the necessaryadditional movement to raise the rack bar to the limit of its upi Yardmovement; or by simply rocking;` the line space lever to its limit thelirst stop P on the rack bar will engage the niain stop O. Thisconstruction thus provides for either the ordinary column stop orselective stop systems of tabulating. 'lt is not so' rapid as a.selective stop system having a series of separate keys, but itaccomplishes the purpose within a space that does not admit ot' a seriesof separate stop keys7 and it does not require a carriage retardingdevice thereby further economizing room and expense.

rlhe main tabulating stop t) is rigidly connected to or 'formed with yaplate g which is secured to the upper end of the bracket el by screws Q,Fig. 9, passing through in clined slots in the plate. it spring' Q2connected to the plate g and to the bracket acts to retain the stopnormally in the elevated position shown. 1When one ot the adjustabletabulating stops strikes the stop (l the stop plate is moved to' theleft and d owmvirrdly, so that the rack bar will, when the l-ine spacelever is releaseoh rengage the feed pinion before the adjustable stop isdisengaged from the main stop 0. This per' mits the line space lever tobe, released a.c soon as the adjustable stop strikes `the stop withoutdanger oi' farther movement oi the carriage. I y y g3 represents a bellcrank lever which i: pivotally mounted on the rear side of the brackete, see Fig'. 9, and has an upper arm provided with a roller adapted totravel on 'the under side of the rack bar in rear ot the rack teeth,when the rack bar is in ,iis normal feeding; position. When the rari;-bar is raised to release the carriage, a con` cealed spring swings thebell crank "lever upwardly and a tooth on its lower arm enters betweentwo adjacent teeth of the feed pinion and locks the pinion andcarriageescapement :troni movement, so that when the rack loar isreleased it will properly engage the feed pinion.

R represents an auxiliary carriage release lever which is pivoted on theleft hand end of the carriage and is adapted to engage the racksupportinglever L for lifting the rack to permit either margin stop topass the center stop. A pin "r, Fig'. 6, limits the down ward movementof the auxiliary releas lOl lil

lever, so that the rack cannot he raised hy this lever high enough tocause the adjustable stops ll' l to engage the tahulating stop il ln thepreferred construction, as shown,

4 the auxiliary release lever R will ordinarily he used to release thecarriage, or line lock,

as the tahulator stops cannot he brought into action hf, that lever, hutthe line space lever can he used tor releasing the carriage, and linelock, as well as for tabulating, and

'after alittle practice, the operator learns to move the line spacelever the limited distance required tor this purpose without bringingthe tahulating mechanism into ac tion.

From the above, 'it Will he seen-that a line space lever of populartorni and movement,

and the rack bar, have been combined with other parts in such mannerthat the line space lever is used to actuate a series ot tahulatorstops, either successively or selectively at Will, and also to releasethe carriage from its margin stops, or line loclr, in addition to itsuse for line spacing and returning the carriage for the nest line.
